Average Function
Great! Thank you very much for your help!
"JW" wrote: The 1 is an optional argument for the return type. Taken from Excel help: 1 or omitted = Numbers 1 (Sunday) through 7 (Saturday). Behaves like previous versions of Microsoft Excel. 2 = Numbers 1 (Monday) through 7 (Sunday). 3 = Numbers 0 (Monday) through 6 (Sunday). DaS wrote: After messing around with it, I got it. Thank you very much for your help. For the sake of knowledge, what does the ....,1) represent? "JW" wrote: All Ctrl+Shift+Enter entered. Monday: =AVERAGE(IF(WEEKDAY(B2:B25,1)=2,E2:E25)) Tuesday: =AVERAGE(IF(WEEKDAY(B2:B25,1)=3,E2:E25)) Wednesday: =AVERAGE(IF(WEEKDAY(B2:B25,1)=4,E2:E25)) etc etc DaS wrote: So to change the date to do Tuesday I need to change the 1 or the 2? so Tuesday will be ...(WEEKDAY(B2:B25,2)=2,...? Is that right? I've been messing around with it and now I get the #NUM! statement. Thanks JW "JW" wrote: One way (Array entered, Ctrl+Shift+Enter) =AVERAGE(IF(WEEKDAY(B2:B25,1)=2,E2:E25)) The above formula will calculate the average of E2:E25 where the weekday in B2:B25 is equal to Monday. To do Tuesday, Wednesday, etc, simply change the WEEKDAY(B2:B25,1)=2 portion to whatever day of the week you are after. DaS wrote: In column B I have the dates listed from 01/01/07 through 10/31/2007. In column E I have totals for each day. What I would like to do is have an average for each day of the week, i.e., Mondays from 01/01/2007-10/31/2007 = 219, Tuesdays from 01/01/2007-10/31/2007= 250 and so on. I know that I will have to have a separate cell doing it's own calculation for each weekday, I'm just not that savvy working with the Sumifs, countifs, or day functions. Thanks! |
